Another of the illustrations shows the tool in use and theresults which can be accomplished by it. In the upper left handcomer is shown the die in use cutting new threads on thebroken part. This die is made so that it can be easily andquickly operated under a car or in places where very littlespace is available. It usually takes about three minutes to cutthe new threads. In the upper right hand corner the repairtool is shown in position after the threads have been facing and counterboring of the damaged part are accom-plished in one operation, the time necessary being from four tosix minutes.

LANDIS STATIONARY PIPE DIE HEAD comparatively short lived, as a few grindings will cause thelength of thread to fall below the standard. This objection iseliminated with this die, since the cutting contour is always thesame, this being due to the fact that the chasers are ground ontheir inner ends and never on the bevel surfaces which form thethroat. As one set of dies covers the entire range on all sizes ofstandard pipe where the pitch is the same, it is unnecessary to A new stationary pipe die head that is simple in constructionand is applicable to certain pipe machines of the rotating pipetype has been perfected by the Landis Machine Company,Waynesboro, Pa. A general idea of its operation may be ob-tained from the illustration. The head is composed o
